Yes, this is the direction we want to explore. Grey market mitigation
is (IMO) important enough to warrant changes. I'm trying very hard to
make sure the changes proposed will not derail production.

I believe the effect of that would be to have a white-on-white x-o
graphic. If you mean to change the overall green colour to white, I'm
assuming we're well past that point. The reason using the x-o graphic
on the cover of the laptop as differentiator is attractive is because we
already have mechanisms for changing that set of colours for each laptop
(and have tested extensively with the resulting machines). Reserving a
single colour distinctive colour combination *should* just be a matter
of altering the control file being fed to the machine to exclude that
one combination (as far as I am aware).
We'll have to talk to the people working on production ASAP to make such
a change happen, and confirm that it's doable. First want to be sure
it's a desirable thing and worth the effort, your comments are very
helpful toward that end.
